In this work the coupled electrochemical-thermal model for a lithium-ion battery (LIB) based on porous electrode theory has been extended with contributions coming from exothermic side reactions based on an Arrhenius law to model abuse mechanisms, which could lead to a thermal runaway. These extensions have been modeled with a constant fuel model and for specified current profiles and exterior ...

This project modeled an industrial chromium plating process for automotive components. The process was modeled via the COMSOL Multiphysics® Electrodeposition Module. The simulation examined the effect of solution conductivity, electrode spacing, and anode height utilizing a factorial design approach. A sensitivity analysis was used to study the effect of these variables on the thickness value at ...

A lithium-ion battery comprises of two intercalating electrodes separated by a membrane, sandwiched between aluminum and copper current collecting plates. The battery performance depends upon several parameters and its operating conditions. In this work we developed a model for a lithium iron phosphate battery and validated our results with experimental charge-discharge curves. We however note ...

The adoption of micro- and nanostructured electrodes is a promising technique to improve the performance of Li-ion battery, which increases the electrode surface area and improves the efficiency of ion exchange between the electrode and electrolyte. This performance improvement is supported by the results of our numerical simulation based of a Li+ battery in COMSOL Multiphysics® software. The ...

In this paper, the cyclic voltammetry behavior of Ferrocyanide/Ferricyanide, which is commonly used for electrochemical DNA detection experiment, was studied in the commercial EQCM-D setup (Q-sense) using the COMSOL Multiphysics. The model was established in a 3D geometry of QCM liquid cell. The simulation shows depletion of concentration of ferrocyanice following applied electrode ...

There is great interest in developing all-solid-state lithium-ion batteries. They are ideal micro-power sources for many applications in portable electronic devices, electric vehicles and biomedical engineering. It is known that all-solid-state lithium-ion batteries are often fabricated by thin film methods, with thicknesses in the range of a few micrometers. Since porous electrodes are not ...

PEM Fuel Cells’ durability and performance can be increased using an ejector based hydrogen recirculation system. In this work, a CFD model has been implemented to simulate the flow within an ejector used to recirculate hydrogen in PEM Fuel Cell systems. The model has been validated experimentally and has been used to design and manufacture an ejector that will be implemented in a fuel cell test ...

Additive manufacturing uses 3D printing to build physical parts from CAD-based designs. The technology includes fused deposition modeling (FDM) and selective laser sintering (SLS) methods. 3-D printing is of particular interest for smaller, one-of-a-kind, customizable products. A cube satellite (CubeSat) containing fiber reinforced SLS parts has been successfully launched (Ref 1). Lower ...

When it comes to study the behavior of the secondary batteries, physics-based models are more representative of the real behaviour than equivalent circuit models, especially for the estimation of the life and capacity fading. On the other hand, the complexity and computational cost of sophisticated physics-based models like pseudo two-dimensional (P2D) models justify the use of more simplified ...
